MINE AIR VENTILATION AND CONDITIONING PLANT Russian patent published in 2017 - IPC E21F1/08 

FIELD: mining.

SUBSTANCE: invention relates to mining and oil industry. Mine plant comprises a ventilation unit with a combined inlet box, outlet diffusers of which are combined into one air duct for air supply into the well. Inlet headers of the ventilation unit are arranged on ends of the combined inlet box, and a combined intake device includes air filters, bypass channel sections at the inlet and the outlet, a cooling section of the air conditioning system, a vertical intermediate mixing chamber, a heating section of the air conditioning system. Sections of the bypass channel are equipped with an inlet and an outlet air valves. Sections of cooling and heating are also equipped with inlet and outlet air valves, between which there are an air cooling heat exchanger and an air heating heat exchanger. Herewith the plant is equipped with a steam-ejector refrigerating machine serving as a source of cooled water for cooling the process heat carrier of the air conditioning system and a heat station with heat exchangers of heating and cooling of the process heat carrier of the air conditioning system. Herewith for cooling water in the steam-ejector refrigerating machine on the plant section opposite to the combined intake device there is a ventilation cooling tower.

EFFECT: technical result is improvement of reliability and efficiency of the plant.
